Abstract: An image processing element 4 (image processing apparatus) of the present invention, the benchmark value calculation element 41 calculates a benchmark value indicating the unevenness level of the brightness value from the brightness distribution in the proximity of pixels and the area-dividing element 43 sets up the enhancement level (property of the filter or intensity of the filter) corresponding to the unevenness level of the benchmark value per se every divided divided-area, so that an adjustment corresponding to the level of the brightness value is unnecessary and the enhancement processing can be executed in high-accuracy from a low-brightness portion to a high-brightness portion. In addition, no setting depending on the brightness value is mandatory, so that a fine setting and a fine adjustment prior to imaging is unnecessary and a highly-accurate processing can be executed securely even when the imaging environment and an imaging condition change.

Abstract: A representative value calculator calculates a representative value which is a luminance value representing a main inspection object area from an input image. On the other hand, an image divider divides an image area of the input image, and sets a plurality of divided ranges. A factor calculator calculates a tone conversion factor for enhancing or suppressing contrast adjacent the representative value calculated by the representative value calculator for each area (each divided area) divided by the image divider. A tone converter converts the tone of each pixel of the input image based on the tone conversion factor for the range divided by the image divider, which range includes a pixel for image processing, and ranges adjacent that range. As a result, the contrast of the area for which enhancement is desired can be enhanced optimally.

Abstract: A radiological image processing apparatus of this invention includes a separating device, an adjusting device and a removing device. Since a corrected image is generated using the radiological image taken through an object under examination, each image can be acquired by one radiographic operation without acquiring data for grid correction beforehand. The radiological image taken through the object is separated into a grid image and a non-grid image, and a corrected image is generated by adjusting intensity of the grid image on real space based on the non-grid image. Thus a high-precision correcting process is realized by one radiographic operation.
